Explain network timings

[paulirish]

@Garbee do you have a ticket tracking the network stuff you're working on?

Regardless I wanted to capture these items, so they go into the docs.

What do the various timings in network mean?

• networking - What does Chrome Network Timings really mean and what does affects each timing length? - Stack Overflow
  • garbee's awesome answer
• Issue 476749 - chromium - DevTools: network explain empty bars preceeding request
  • big deep dive into chrome to answer what queuing and stalled are.
• google chrome - What the emptiness mean in devtools timings? - Stack Overflow
  • my simplified answer on queuing

I don't have anything tracking the DGC work, actually forgot about it. Let's assign this to me and it can serve as an action item and bucket of things to cover.

Thanks for digging in and getting the answers to the hollow bars! So good to know what it means finally. :smile:

bump!

That part needs some further clarification for the curious minds.

And I agree with Paul that instead of naming it "queueing"/"stalled", using "postponed"/"awaiting socket" time ranges would make the waterfall diagram much clearer to understand (to me at least).

I believe we discussed renaming before in the issue tracker. Decided against it since what we have aligns with other browsers and is fairly standard technically speaking. If you wish to discuss that again though, you can file a new issue (since I'm having trouble finding the old issue) for getting things renamed.

Hmm. I believe we're fine with renaming.

[v0lkan]

Well I "feel" the renamed version is a better fit; however I'm not feeling too strong to open a new issue if you've already discussed this and settled with a decision.

At any rate, naming is hard.
